Perhaps you should try some spelling variations:
nhanh mang » nhanh lang, nhanh quang, nhanh thang
tieu sach » chieu sach, dien sach, te sach
hanh mang » hanh trang, nhanh lang, thanh hang
cua nhung » va nhung
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan tap » toan ban

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: theo tieu sach - ((hanh mang) OR (nhanh mang)) cua nhung ((cong dan) OR (cong tan)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - ((hanh mang) OR (nhanh mang)) cua nhung ((cong dan) or (cong tan)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - ((hanh mang) OR (nhanh mang)) cua nhung ((cong dan) or (cong tan)) toan tap*.
